Robson was engaged to deliver a significant package of civil works for the Liddell Battery Energy Storage System (BESS) for our client, Enerven (for asset owner AGL).
Liddell BESS is a critical project supporting grid stability and the energy transition in New South Wales. Building on Robson’s strong performance at the Eraring BESS, the team was brought on early to collaborate with the client and delivery partners, enabling works to progress within a tightly constrained and highly complex and, at times, live energy environment.
The project required close coordination across multiple stakeholders and interfaces, including live electrical assets, to achieve defined handover milestones supporting timely battery installation, commissioning and energisation.

Highlights
- Dealing with unsuitable material - Robson developed and implemented remediation strategies in collaboration with environmental consultants, including removal, re-location and capping to allow works to proceed safely.
- Works were undertaken adjacent to live and commissioning battery assets, requiring strict compliance, additional exclusion zones, spotters and electrical permitting processes.
- The project required daily coordination across multiple parties including AGL, Fluence, Enerven and numerous subcontractors.
- Program constraints - A hard commissioning deadline required careful staging, parallel work fronts and diversification of subcontractors to maintain progress.
- Use of a collaborative day works delivery model during design finalisation
